Quarter Circle 10 parts are designed to work within mil-spec perimeters. However, for optimum performance we recommend using QC10 parts for all your core elements, (receivers, bolt, barrel and adjustable buffer system).

Made for- Not Modified. Every QC10 product is engineered specifically for pistol caliber ammunition, not modified from an existing platform, increasing functionality, reliability and overall performance.

Any orders containing lower receivers require a verified FFL dealer to make the transfer. Lower receivers will not be shipped until QC10 has your dealer's license on file. Please contact your desired dealer about sending us a copy of their license.

CALIFORNIA BUYERS: Please check with your transferring dealer before ordering. Many CA dealers are unwilling to process lower receiver transfers.

Important Warranty Note: If you intend to register your Quarter Circle 10 firearm as an NFA weapon, test it thoroughly before doing so in a Title 1 Configuration. Once you Form 1 or Form 2 it, you are legally the manufacturer, and we cannot service the firearm. Should your firearm require warranty replacement we can only replace it with a Title I receiver and we are not responsible for tax stamps or NFA fees.
